MSMs post 8x50 have 2Mb at the beginning of RAM reserved for shared memory. Since the kernel hasn't typically been told this RAM exists, PHYS_OFFSET has been set to 0xN0200000 and the memory atags passed to the kernel have matched. This doesn't play nicely with things such as AUTO_ZRELADDR, which doesn't work at all, and dynamic phys to virt, which requires an MSM specific workaround. Work around these issues by telling the kernel RAM starts at 0xN0000000 (it actually does) and fixup the atags from the bootloader (if necessary) to say the same. In addition, make sure to set TEXT_OFFSET at least 2Mb beyond the start of RAM so that the kernel doesn't end up being decompressed into shared memory. After doing this, AUTO_ZRELADDR should work on MSM with no problems and ARM_PATCH_PHYS_VIRT_16BIT should no longer be necessary.

With the UM_SIGNAL alignment fault mode, no siginfo structure is passed to userspace. POSIX specifies how siginfo_t should be populated for alignment faults, so this patch does just that: * si_signo = SIGBUS * si_code = BUS_ADRALN * si_addr = misaligned data address at which access was attempted Signed-off-by: NDave Martin <dave.martin@linaro.org> Acked-by: NNicolas Pitre <nicolas.pitre@linaro.org> Acked-by: NKirill A.

Currently, it's possible to set the kernel to ignore alignment faults when changing the alignment fault handling mode at runtime via /proc/sys/alignment, even though this is undesirable on ARMv6 and above, where it can result in infinite spins where an un-fixed- up instruction repeatedly faults. In addition, the kernel clobbers any alignment mode specified on the command-line if running on ARMv6 or above. This patch factors out the necessary safety check into a couple of new helper functions, and checks and modifies the fault handling mode as appropriate on boot and on writes to /proc/cpu/alignment. Prior to ARMv6, the behaviour is unchanged. For ARMv6 and above, the behaviour changes as follows: * Attempting to ignore faults on ARMv6 results in the mode being forced to UM_FIXUP instead. A warning is printed if this happened as a result of a write to /proc/cpu/alignment. The user's UM_WARN bit (if present) is still honoured. * An alignment= argument from the kernel command-line is now honoured, except that the kernel will modify the specified mode as described above. This is allows modes such as UM_SIGNAL and UM_WARN to be active immediately from boot, which is useful for debugging purposes.

The file mm/proc-arm946.S contains a typo and is missing a structure member in __arm946_proc_info. The former prevents compilation and the latter causes problems during boot. It is likely this file was manually copied from a similar file and not tested, then later updates to the *_proc_info structures missed this file. This patch will apply (with offset) with or without the recent macro unification work that has been done in this directory. This was verified against linux-next/stable last week.

由 Michael Schmitz 提交于
Based on an original patch from Michael Schmitz: Because mem_init() is now called before device init, devices that rely on ST-RAM may find all ST-RAM already allocated to other users by the time device init happens. In particular, a large initrd RAM disk may use up enough of ST-RAM to cause atari_stram_alloc() to resort to __get_dma_pages() allocation. In the current state of Atari memory management, all of RAM is marked DMA capable, so __get_dma_pages() may well return RAM that is not in actual fact DMA capable. Using this for frame buffer or SCSI DMA buffer causes subtle failure. The ST-RAM allocator has been changed to allocate memory from a pool of reserved ST-RAM of configurable size, set aside on ST-RAM init (i.e. before mem_init()). As long as this pool is not exhausted, allocation of real ST-RAM can be guaranteed. Other changes: - Replace the custom allocator in the ST-RAM pool by the existing allocator in the resource subsystem, - Remove mem_init_done and its hook, as memory init is now done before device init, - Remove /proc/stram, as ST-RAM usage now shows up under /proc/iomem, e.g. 005f2000-006f1fff : ST-RAM Pool 005f2000-0063dfff : atafb 0063e000-00641fff : ataflop 00642000-00642fff : SCSI Signed-off-by: NMichael Schmitz <schmitz@debian.org> [Andreas Schwab <schwab@linux-m68k.org>: Use memparse()] [Geert: Use the resource subsystem instead of a custom allocator] Signed-off-by: NGeert Uytterhoeven <geert@linux-m68k.org>

The address that's passed to _sparc_find_resource() should always be the start address of a resource: - iounmap() passes a page-aligned virtual address, while the original address was created by adding the in-page offset to the resource's start address, - sbus_free_coherent() and pci32_free_coherent() should be passed an address obtained from sbus_alloc_coherent() resp. pci32_alloc_coherent(), which is always a resource's start address.
